I was in a 5 man dungeon and you can see the unit frames in the top left. The player frame is showing with the pet bar directly below it. You can see the target frame and then the target of target frame to the right of it.

I have my focus/energy bar right above my main action bar in the center. I also have 4 colorful bars below my main action bar, that is the addon NeedToKnow and I use it to track my dot's and cd's.

IMGUR walkthrough for convenient thumbnailing:
Go to www.imgur.com and upload your image. Once done, click 'large thumbnail' over on the right side of the screen, where all of the embed links are. Once there, copy the 'linked image url code'! Use that for your post, and voila.

As the old Hunter UI thread has long since fallen to the bottom, I'm going to be stickying this one! I'm also editing the post with a little tutorial on how to use imgur, as it's the most convenient way to link to images without opening new windows or making them too huge.
